Abstract

A process for producing lipid membrane structures (vesicles or liposomes) is disclosed, wherein a solution of bilayer forming compounds in a narrowly-defined two component solvent system is dispersed in an aqueous solution and, subsequently, at least a portion of that solvent system is stripped off. This process permits the readily-reproducible production of lipid membrane structures under gentle processing conditions, ideal for use when they contain pharmaceutically-active materials.
